To solve the problem step by step, we will analyze the motion of the scooter, which accelerates and then decelerates to cover a distance of 1.5 km. ### Step 1: Understand the given data - Maximum acceleration (α) = 5 m/s² - Maximum retardation (β) = 10 m/s² - Total distance (s) = 1.5 km = 1500 m ### Step 2: Define the motion phases ...
